Abstract
Description
Technical Field
[0001] This invention relates to the field of material conveying technology, specifically to a multi-sample solid powder adding mechanism and its adding method. Background Technology
[0002] In chemical, food, and other industrial production processes, it is necessary to add various solid powder materials simultaneously according to certain formula requirements. Due to the differences in hygroscopicity among different materials, some highly hygroscopic powder materials easily absorb moisture from the environment, increasing their own humidity and causing them to clump together or agglomerate during mixing with other materials. In addition, different types of powder materials have different particle sizes, shapes, and densities, which may lead to stratification or aggregation after mixing. The above-mentioned agglomeration and stratification phenomena can cause a temporary static equilibrium when the mixture reaches the discharge port, thus clogging the discharge port and preventing the mixture from being discharged on its own, seriously affecting the efficiency of the mixture addition. Summary of the Invention

[0047] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.
[0048] Please see Figure 1 and Figure 2 The present invention discloses a multi-sample solid powder adding mechanism, including a lower cover 100, an upper cover 200, a feeding channel 300, a dispersing mechanism 600, a clearing mechanism 700, a reciprocating drive assembly and a scattering mechanism 800.
[0049] Please refer to Figure 2 The lower cover 100 includes an integrally connected lower cone 110 and discharge cylinder 120; the upper cover 200 is rotatably connected to the lower cover 100.
[0050] Multiple sets of feeding channels 300 are provided and are circumferentially distributed within the upper cover 200;
[0051] Please see Figure 2 , Figure 6 and Figure 7 The dispersing mechanism 600 is disposed inside the discharge cylinder 120 and includes an inner support ring 610, an outer support ring 630, and a rotary drive assembly. A plurality of blades 620 are circumferentially arranged between the inner support ring 610 and the outer support ring 630. The outer support ring 630 is rotatably connected to the inner wall of the discharge cylinder 120. The rotary drive assembly is disposed on the discharge cylinder 120 and is used to drive the outer support ring 630 to rotate.
[0052] Please see Figure 6 and Figure 7 The unblocking mechanism 700 is installed inside the discharge cylinder 120, including a tamping rod 710 and an unblocking component 720 installed at the lower end of the tamping rod 710. The tamping rod 710 movably passes through the inner support ring 610.
[0053] The reciprocating drive assembly is mounted on the inner support ring 610 and is used to drive the tamping rod 710 to reciprocate and extend.
[0054] Please see Figure 2 and Figure 3 The scattering mechanism 800 is disposed inside the lower cone 110 and includes several sets of circumferentially distributed scattering buckets 810. The scattering buckets 810 are rotatably installed inside the lower cone 110. A first sector gear 820 is disposed on the scattering bucket 810, and a first rack 830 that meshes with the first sector gear 820 is disposed on the tamping rod 710.
[0055] Specifically, the rotary drive assembly drives the dispersing mechanism 600 to rotate as a whole, thereby causing the blades 620 to rotate continuously within the discharge cylinder 120; under the action of the reciprocating drive assembly, the tamping rod 710 moves up and down reciprocally, thereby driving the unblocking part 720 at the lower end of the tamping rod 710 to move up and down in and out of the discharge cylinder 120; under the transmission of the first rack 830 and the first sector gear 820, the tamping rod 710 drives each scattering bucket 810 to rotate and swing up and down reciprocally.
[0056] Different solid powder materials are fed into the cavity formed by the lower cover 100 and the upper cover 200 through the corresponding feeding channel 300. The solid powder materials fall onto the corresponding throwing bucket 810, which swings upward to throw the solid powder materials towards the central area, causing the solid powder materials to collide and merge with each other. The mixed solid powder materials then fall into the discharge cylinder 120, where the continuously rotating blades 620 further disperse the mixed solid powder materials. The dispersed mixed solid powder materials are discharged from the outlet of the discharge cylinder 120. During the material discharge process, the tamping rod 710 drives the unblocking part 720 at the lower end to tamp the outlet of the discharge cylinder 120 up and down, thereby continuously disrupting the static balance of the material at the outlet of the discharge cylinder 120 and preventing the material from clogging at the outlet of the discharge cylinder 120.
[0057] Further, please refer to Figure 1 , Figure 2 and Figure 4 The rotary drive assembly includes a drive motor 640 installed on the outside of the discharge cylinder 120. The output end of the drive motor 640 is connected to a drive gear 641. The outer support ring 630 is provided with a driven gear 631 that meshes with the drive gear 641. An opening for accommodating the drive gear 641 is provided on the side wall of the discharge cylinder 120.
[0058] The drive motor 640 drives the drive gear 641 to rotate. Under the meshing transmission of the drive gear 641 and the driven gear 631, the entire dispersing mechanism 600 is driven to rotate circumferentially within the discharge cylinder 120 to achieve the dispersing treatment of materials.
[0059] Furthermore, please refer to Figure 7 , Figure 9 and Figure 10 The reciprocating drive assembly includes a screw frame 740 fixed to the lower end face of the inner support ring 610, a push rod 750 adapted to the screw frame 740 fixed on the tamping rod 710, a limiting plate 760 located above the inner support ring 610 fixed on the tamping rod 710, and a thrust spring 770 provided between the limiting plate 760 and the inner support ring 610, the thrust spring 770 being movably sleeved on the tamping rod 710;
[0060] When the drive motor 640 drives the dispersing mechanism 600 to rotate circumferentially to disperse the solid powder material, the screw frame 740 also rotates synchronously. Since the push rod 750 is adapted to the spiral surface of the screw frame 740, the screw frame 740 can axially restrict the push rod 750. As the screw frame 740 rotates, it forces the push rod 750 to gradually climb along the spiral surface, that is, the push rod 750 gradually moves downward away from the inner support ring 610, thereby driving the tamping rod 710 and the limiting plate 760 to move downward. The thrust spring 770 is compressed, which in turn drives the unblocking component 720 to tamp and unblock the outlet of the discharge cylinder 120. At the same time, under the meshing transmission of the first rack 830 and the first sector gear 820, the throwing bucket 810 is driven to flip upward and throw the solid powder material.
[0061] As the push rod 750 continues to move away from the inner support ring 610 relative to the screw frame 740, until the push rod 750 reaches the end of the screw frame 740 away from the inner support ring 610 and disengages from the screw frame 740, since the screw frame 740 no longer axially restricts the push rod 750, the limit plate 760 is pushed upward under the elastic force of the thrust spring 770, which in turn drives the tamping rod 710 and the push rod 750 to move upward synchronously until the push rod 750 contacts the inner support ring 610 again to complete the reset. During the upward movement of the tamping rod 710, the unblocking part 720 at the lower end drives the discharge cylinder 120 to tamp and unblock the outlet. At the same time, under the meshing transmission of the first rack 830 and the first sector gear 820, the throwing bucket 810 is driven to flip downward to reset in order to receive the subsequently falling solid powder material.
[0062] In this way, with the continuous rotation of the dispersing mechanism 600, the reciprocating drive component can drive the tamping rod 710 to move up and down, thereby realizing the continuous dispersing of solid powder materials by the scattering mechanism 800 and the continuous unblocking of the outlet of the discharge cylinder 120 by the unblocking component 720.
[0063] Additionally, to improve the unblocking effect of the unblocking component 720 on the outlet of the discharge cylinder 120, please refer to [link / reference needed]. Figure 9 and Figure 11 The unblocking component 720 includes several sets of radial unblocking frames 721 evenly distributed on the tamping rod 710 in the circumferential direction, and several sets of annular unblocking frames 722 are distributed radially between adjacent radial unblocking frames 721.
[0064] When the tamping rod 710 moves up and down, it drives the radial unblocking frame 721 and the annular unblocking frame 722 to move up and down synchronously. The radial unblocking frame 721 can cut the accumulated mixture radially, while the annular unblocking frame 722 can cut the accumulated mixture circumferentially. By utilizing the superposition of radial and annular cutting, the static equilibrium state of the accumulated material is broken in all directions, thereby improving the unblocking effect.
[0065] In one embodiment, considering the different hygroscopic properties of various solid powder materials, some highly hygroscopic solid powder materials may have high moisture content, which may cause them to easily clump together or adhere and agglomerate when mixed with other types of solid powder materials, thus affecting the smoothness of the discharge. Therefore, please refer to... Figure 2 and Figure 6 The upper cover 200 includes an integrally connected first upper cone 210, transition cylinder 220, and second upper cone 230, the second upper cone 230 being rotatably connected to the lower cone 110; the feed channel 300 is disposed inside the first upper cone 210; a conical grinding disc 400 is fixedly installed inside the lower cone 110, a heating plate is disposed on the grinding surface of the conical grinding disc 400, and a plurality of grinding mechanisms 500 are circumferentially disposed on the inner wall of the second upper cone 230;
[0066] Specifically, different solid powder materials are fed into each feed channel 300. The solid powder materials fall onto the lower conical grinding disc 400 through the transition cylinder 220. The heating plate on the conical grinding disc 400 heats and dries the solid powder materials on the grinding surface. At the same time, the upper cover 200 rotates relative to the lower cover 100, thereby driving the grinding mechanism 500 to rotate circumferentially relative to the conical grinding disc 400, grinding and crushing the solid powder materials on the conical grinding disc 400. After crushing and drying, the internal moisture of the agglomerated solid powder materials is removed, thereby reducing the humidity of the solid powder materials and preventing them from sticking together during subsequent mixing.
[0067] Further, please refer to Figure 8 The grinding mechanism 500 includes a mounting frame 510 and a rotating shaft 520. The mounting frame 510 is fixedly mounted on the second upper cone 230, and the rotating shaft 520 is rotatably mounted on the mounting frame 510. Several cleaning plates 530 are evenly distributed circumferentially on the rotating shaft 520, and a grinding roller 540 is provided at the end of the rotating shaft 520 away from the transition cylinder 220.
[0068] When the upper cover 200 rotates relative to the conical grinding disc 400, it drives the grinding roller 540 to roll circumferentially along the grinding surface of the conical grinding disc 400, thereby grinding the solid powder material on the conical grinding disc 400. While the grinding roller 540 is rolling, it drives the cleaning plate 530 to rotate synchronously through the rotating shaft 520, thereby cleaning the solid powder material on the conical grinding disc 400, thereby gathering the solid powder material towards the moving side of the upper cover 200, which facilitates the concentrated grinding of the solid powder material.
[0069] It should be noted that, during the process of feeding solid powder material onto the conical grinding disc 400 through the feeding channel 300, the upper cover 200 rotates continuously. Therefore, the falling solid powder material can evenly cover the grinding surface of the conical grinding disc 400 in a circumferential direction, thereby increasing the contact area between the solid powder material and the heating plate and improving the drying efficiency. In practical applications, in order to ensure the drying effect, the upper cover 200 can pause rotation when drying the solid powder material, so that the solid powder material and the heating plate have sufficient contact time to facilitate the rapid drying of moisture. After the set drying time is reached, the upper cover 200 rotates again, driving the grinding roller 540 to grind the solid powder material, while simultaneously driving the cleaning plate 530 to gather the dried solid powder material to one side.
[0070] Furthermore, in order for the grinding roller 540 to fully grind solid powder materials, please refer to... Figure 6 and Figure 8 The conical grinding disc 400 is provided with an annular baffle 410, which is in contact with the grinding roller 540; the annular baffle 410 has a plurality of discharge grooves 420 evenly distributed on its inner circumference; the mounting frame 510 is provided with a scraper 550 on the side away from the corresponding discharge groove 420; the lower end face of the conical grinding disc 400 is provided with a discharge plate 430 that connects to each discharge groove 420, and the discharge plate 430 is located directly above the corresponding scattering bucket 810;
[0071] Solid powder falling from the feed channel 300 is evenly spread on the conical grinding disc 400. Under the sweeping action of the cleaning plate 530 and its own gravity, the solid powder gradually slides down the inclined conical grinding disc 400 and gathers at the annular baffle 410. When the upper cover 200 rotates, it drives the grinding roller 540 to roll along the conical grinding disc 400, so that the grinding roller 540 can fully grind the solid powder. At the same time, it drives the scraper 550 to move circumferentially along the annular baffle 410, thereby pushing the ground solid powder to the corresponding discharge trough 420. Then, the solid powder is discharged into the corresponding scattering hopper 810 through the discharge plate 430 for subsequent scattering.
[0072] Additionally, to prevent solid powder material from adhering to the conical grinding disc 400, please refer to... Figure 6 The upper end of the tamping rod 710 is provided with a plurality of tamping balls 730 that are adapted to the bottom surface of the conical grinding disc 400;
[0073] When the tamping rod 710 rises, it causes the vibrating ball 730 to contact the bottom surface of the conical grinding disc 400, thereby causing the conical grinding disc 400 to vibrate. As the tamping rod 710 moves back and forth up and down, it can cause the vibrating ball 730 to continuously vibrate the conical grinding disc 400, which avoids the solid powder material from sticking to the conical grinding disc 400 during the drying and grinding process, and at the same time promotes the further dispersion and discharge of the solid powder material.
[0074] In another embodiment, considering that continuous feeding may cause material accumulation in the discharge cylinder 120, thereby increasing the congestion in the discharge cylinder 120, and that continuous feeding may also prevent the throwing hopper 810 from continuing to receive the material falling from the conical grinding disc 400 during the upward throwing of material, resulting in some solid powder material not being thrown and fused; therefore, please refer to Figure 2 and Figure 5 It also includes an opening and closing mechanism 900 disposed within the transition cylinder 220. The opening and closing mechanism 900 includes a partition 910 fixed within the transition cylinder 220, which divides the transition cylinder 220 into several storage spaces, each of which corresponds to a feeding channel 300. A sealing plate 920 is rotatably disposed at the bottom of each storage space. A telescopic sleeve 930 is hinged to the upper end face of the sealing plate 920. A telescopic rod 940 is hinged to the partition 910. The telescopic rod 940 is slidably connected to the telescopic sleeve 930. A tension spring 950 is connected between the telescopic rod 940 and the telescopic sleeve 930. A counterweight 960 is disposed on the telescopic sleeve 930.
[0075] Specifically, when the upper cover 200 rotates at a certain speed, under the action of centrifugal force, the counterweight 960 moves radially away from the axis of the transition cylinder 220, thereby causing the telescopic rod 940 to extend out of the telescopic sleeve 930, the tension spring 950 to be stretched, and the sealing plate 920 to be flipped downward and opened, so that the solid powder material in the storage space is discharged onto the conical grinding disc 400.
[0076] When the upper cover 200 stops rotating or the speed is low, the centrifugal force of the counterweight 960 is insufficient to overcome the tension of the tension spring 950, thereby causing the telescopic sleeve 930 to be pulled back, which in turn causes the sealing plate 920 to flip upward and close.
[0077] By switching the motion state of the upper cover 200, the sealing plate 920 is periodically opened and closed to intermittently feed material into the conical grinding disc 400.
[0078] When one cycle of intermittent feeding is completed, the solid powder material in the transition cylinder 220 falls onto the conical grinding disc 400, and after drying and grinding, the solid powder material is discharged from the corresponding discharge plate 430.
[0079] The scattering hopper 810 receives the falling solid powder material, then flips the solid powder material upward and scatters it out, so that the various solid powder materials are fully mixed. Then the scattering hopper 810 flips back to its original position to receive the material of the next cycle. The mixed material after scattering and scattering continues to fall into the discharge cylinder 120 for subsequent dispersing treatment.
[0080] It should be noted that by setting an intermittent feeding opening and closing mechanism 900, and keeping the feeding rhythm synchronized with the actions of the grinding mechanism 500, the unblocking mechanism 700 and the scattering mechanism 800, the intermittently fed solid powder materials can be fully dried, ground, blended and dispersed, so that the various solid powder materials can be mixed more evenly and uniformly, while avoiding the accumulation of mixed materials in the discharge cylinder 120.
[0081] In a further embodiment, considering the reciprocating motion of the throwing mechanism 800, it is impossible to continuously and uninterruptedly throw solid powder materials. Solid powder materials can only be thrown out when the throwing bucket 810 is flipped upward. In order to avoid missing the throwing process of some solid powder materials, the throwing bucket 810 needs to be flipped downward to the receiving position when the solid powder materials on the conical grinding disc 400 fall. When the conical grinding disc 400 stops discharging, the throwing bucket 810 can flip upward and throw out the received solid powder materials.
[0082] It is understandable that the discharge rhythm of the conical grinding disc 400 is determined by the movement cycle of the scraper 550, and the movement cycle of the scraper 550 is related to the movement rhythm of the upper cover 200. Therefore, in order to ensure that the discharge rhythm of the conical grinding disc 400 is compatible with the action of the scattering bucket 810, the movement rhythm of the upper cover 200 can be adjusted accordingly.
[0083] In this embodiment, please refer to Figure 1 and Figure 12 It also includes a reciprocating transmission mechanism 1000, which includes a fixed plate 1100 mounted on the lower cover 100, a turntable 1200 rotatably mounted on the fixed plate 1100, and a reciprocating rocker arm 1400 rotatably mounted on the fixed plate 1100. The turntable 1200 is connected to the output end of the drive motor 640 through a transmission belt 1300. The reciprocating rocker arm 1400 has a through groove 1410 at one end facing the turntable 1200. A lever 1210 is eccentrically provided on the turntable 1200 and is movably embedded in the through groove 1410.
[0084] The reciprocating rocker arm 1400 is provided with a second sector gear 1420 at one end away from the turntable 1200; a sliding sleeve 1600 is provided on the fixed plate 1100, and a second rack 1500 that meshes with the second sector gear 1420 is slidably disposed inside the sliding sleeve 1600.
[0085] A third rack 1700 is fixedly connected to the second rack 1500 via a connecting bracket 1800, and a gear ring 231 that meshes with the third rack 1700 is provided on the upper cover 200.
[0086] Specifically, the drive motor 640 drives the turntable 1200 to rotate via the transmission belt 1300. Under the matching action of the lever 1210 and the through slot 1410, the reciprocating swing arm 1400 can be driven to reciprocate and swing relative to the fixed plate 1100. Under the meshing transmission of the second sector gear 1420 and the second rack 1500, the second rack 1500 can be driven to reciprocate and move horizontally within the sliding sleeve 1600. Furthermore, under the meshing transmission of the third rack 1700 and the gear ring 231, the upper cover 200 can be driven to reciprocate and rotate relative to the lower cover 100.
[0087] When the upper cover 200 rotates to one side, the sealing plate 920 opens and feeds material into the conical grinding disc 400. The grinding roller 540 grinds the solid powder material on the conical grinding disc 400, while the scraper 550 pushes the ground solid powder material to the corresponding discharge trough 420 to complete the discharge.
[0088] When the upper cover 200 switches from one side to the other, the centrifugal force generated by the counterweight 960 gradually decreases as the rotation speed of the upper cover 200 gradually decreases, causing the sealing plate 920 to gradually close. During the switching process of the upper cover 200, feeding can be paused. In practical applications, the timing of the upper cover 200's switching can be adjusted to match the timing of the flipping and reversing of the scattering bucket 810. That is, when the upper cover 200 switches, the scattering bucket 810 is also in the process of flipping and resetting downwards. In this way, during the time when the opening and closing mechanism 900 pauses feeding, the conical grinding disc 400 also pauses discharging downwards. Only after the scattering bucket 810 is fully reset will the opening and closing mechanism 900 continue feeding, and at the same time, the conical grinding disc 400 will continue discharging downwards, thus avoiding the omission of some solid powder materials from being scattered.
[0089] This invention also discloses a method for adding solid powder to a multi-sample solid powder adding mechanism, comprising the following steps:
[0090] S1. Feed various solid powder materials into their respective feed channels 300;
[0091] S2. The upper cover 200 reciprocates to intermittently feed material to the conical grinding disc 400;
[0092] S3. The grinding mechanism 500 grinds and scrapes the material on the conical grinding disc 400;
[0093] S4. The scattering mechanism 800 performs reciprocating scattering and fusion processing on the materials;
[0094] S5. The dispersing mechanism 600 further disperses the mixture.
[0095] S6. The unblocking mechanism 700 unblocks the discharge cylinder 120 from top to bottom.

The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
